Meet nexos.ai
Although our main HQ is in Vilnius, Lithuania, a big part of our talent community is based in Poland. From engineers to marketing pros, we work together to build the future of AI. Here, you'll find a mix of a local community and ambitious, big-scale innovation in the biggest hyper-growth tech markets right now.
What is nexos.ai
nexos.ai is a single AI platform for all things AI. Serving individuals, SMBs and large companies, we enable teams to work at their full potential by building custom no-code AI agents and automating workflows from a single platform.
Instead of juggling dozens of different AI tools and personal accounts, nexos.ai brings everything into one secure platform. It gives teams a central place to access the best AI models (like ChatGPT, Claude, and Gemini), easily build advanced, actionable AI helpers, all while keeping company data safe and organized.
What keeps us building
Our mission is to empower every business team to work at their full potential by making AI intuitive, accessible, and deeply human.
We’re building a world where technology adapts to people, not the other way around. We envision nexos.ai as the AI productivity engine: a single, unified platform where custom AI agents handle the manual grind, leaving humans free to focus on the work they actually love.
How everything started
When Tesonet Founders needed to implement AI in portfolio companies – Nord Security, Oxylabs, Hostinger, and more – they hit the same wall 95% of global businesses face: AI adoption was slow, costly, unsafe, and delivered no real value to teams.
So they built the solution the market was missing. Born in November 2024, nexos.ai launched with $8 million in seed funding. Next, in 2025, we secured one of Lithuania's largest Series A rounds at $30 million.
Now, we're at a hyper-growth stage, shipping AI products at lightning speed.
We care about our employees
We care that our employees feel good not only at work, but also outside of it. We offer a comprehensive benefits package that supports health, development, and work-life balance. We maintain a friendly atmosphere, organize team-building events and training, and we listen to our team's needs to constantly improve working conditions.
Our recruitment process
Recruitment processes differ depending on specific positions and/or hiring teams. However, they tend to include the following three main stages and usually don’t exceed more than five steps.
Stage 1. Get to know you
We review your application in terms of experience, without unnecessary formalities. What matters is what you do and how you write about it.Stage 2. Technical evaluation
We test each applicant's technical knowledge and problem-solving ability through various assessments: a home task, a technical discussion (up to 1.5 h), or a live coding session (up to 1.5 h). In some cases, our candidates can pick the type of technical evaluation they prefer.Stage 3. Meet the team
The final step is for you to meet the team, discuss your task, and dig deeper into the role you’re applying for. If everyone’s happy with the result, the closing step will be the offer. During this meeting with the team, you may further discuss your technical task, dig deeper into the details of the position and the team’s daily life, and/or have a casual chat just to get to know the people you would be working with. It usually takes up to 1 hour.Hear it from the team: what working at nexos.ai is really like
